T 0 all whom it-mafl/ cohc'ern."

Be it known that I, SOLOMON Mai-ma, a

citizen of the United States, residing at North Adams, in the county of Berkshire and State of Massachusetts, have invented certain new and useful Improvements in PermutationLocks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same.

My invention relates to improvements in looks and latches, and more particulzrrly to those of the permutation type, the object of the invention being to provide a lock of this class which although being of very simple and comparatively inexpensive construction, will be highly efhcient in operation and will be particularly adapted for use upon bureaus, buffets, desks, and any other articles of furniture having a plurality of drawers, doors, or the like, to be" locked in closed position, provision being made where by but one permutation mechanism allows a single lock selector to be so, actuatedfas to open but one or all of the locks of the independent drawers, doors or thelike.

With this general object in view, the invention resides in certain novel features of construction, and in unique combinations of parts to be hereinafter fully described and particularly pointed out in the appended claims. i v

In describing the invention, 1 shall refer to the accompanying drawings wherein like reference characters designate corresponding parts throughout the) several views and wherein Figure 1 isafront elevation ofla desk showing the application of the invention to use; Fig. 2 is a sectional viewas seensubstantially on the two planes indicated by the horizontal portions of the line of Fig. 1, the latch of one of the swinging doors of the desk being released; Fig. 3 is a detail vertical section showing more particularly the construction and disposition of one of the latches which are applied to use for locking the drawers of the desk in closed position Fig. this a horizontal section as seen along the plane indicated by the line 4-4 of Fig. 1, this view illustrati top plan of the permutation meanseontrolling the actuation of the loclr'selectorg Fig. 5 is a, detail vertical longitudinal section taken an the line'st of Fig. isafsiinilar Specificationof Letters Patent.

view as seen" on the line 6-6of Fig. 4, and

Fig 7 is yet another verticallongitudinal section as seen on the plane of the line 77 of F ig. 4. o

lnthe attainment of the desired ends, I provide the several drawers, doors, or the like of the article of furniture with independent locks or latches 1 and, at suitable points, a series of parallel latch releasing plungers 2 is provided, suchplun'gers being (llSPOSQCl' at points spaced around an are or a circle as the case may be, the several plungers being connected by suitable means 3 to the latches, whereby actuation of the former, will release the latter. ()perating in conjunction with the several plungers or other latch releasing members, and having its axis 4- disposed at the center of the are or circle upon which saidmembers are spaced, is a lock selector 5 which is normally spaced from said members, but which may, by proper setting of permutation means, be forced past stop mechanism '7 which normally limits the movement of said selector. After such stop mechanism has been passed, the selector is free to be swung arcuately by the provision of an appropriate handle 8 disposed in position to be grasped by the operator. Upon rotation of said selector to the proper extent, the same is disposed opposits one of the lock releasing members, it being now only necessary to force the selector inwardly to actuate this member, thereby releasing the desired lock. The position of the selector in respect to the plungers or other lock releasing members used, is determined by suitable indicating'means 9 rotatable with the axis of said selector and coacting with a dial or the like carried by a faceplate 10 in advance of which the axis 4 projects, this projecting end' carryingthe handle 8 as well as the indicating means 9.

I havestated that the connections 3 between thelatches 1 and. the plungers 9) may be of any preferred type, but when the latches of a pair of swinging doors D are to be released, such latches being located considerably beneath the plungers' 2, the proper plungers are preferably connected to bell cra'nks'll' from which cables or wires 12 lead around appropriate" guide pulleys to the latches 1, being thus evident that when theproper plungers 2' are actuated in the correct manner, the latches l of the doors D will be released. Slightly diderent construch admaster,- ispreferebly protided arthe releasing of the latches 1 of drawers D, a

plurality of upright levers 13 being shown in the present application as fulcrumed upon a horizontal rod 14 disposed in rear of the several plungers 2, certain of the latter being pivoted to one end of said levers, while the other ends" thereof are connected bycables or wires '15with the locks of said drawersQ Regardless of the type of lock, or

the form of connection between the same and the plungers, properactuation ofthe latter, releases the-formen it being therefore evidentthat it is immaterial what mechanism is-provided for transmitting motion from the plunger to the latch.

As shown most clearly in Figs. 2 and 4: of the drawings, the aXis 4 of the lock selec'tor, 5 is not only rotatably mounted in the front plate 10, but in a bearing plate '16 which is secured to any preferred part of thefurniture equipped with this invention,

said plate 16 likewise serving as means to rotatably support the inner ends of axpair of parallel stopreleasing shafts 17 whose outer ends project through the face plate 10 and are provided with operating handles 18 and indicating means 19'coacting with similarv selector to be shifted against the proper plunger-2 for releasing the desired lock. It will be, evident from Fig. 4", that the stops 22 cannot normally pass the stop disks 20,

since they will abut the same, but when the two disks 20 are properlydisposed by actuation of the handles 18, giving due consideration to the indicators 19. the notches 21 will be so disposed as to allow the'stops'22 to shift therethrough, thus allowing the selector 5 to produce the results above set forth. When the latter has been released, and the axis 4 isrotated to proper position, a coiled spring 23 again shifts the same outwardly, whereupon proper actuation of the handles 19 will so dispose the disks 20 as to again prevent inward movement of the selector. f

' The tvpe of selector may be varied according to the character of the lock in which the same'is disposed. but in most instances it is inthe form of a crank arm extending from the inner'end of the axis or shaft 4: and preferably having a stud 5? adapted to be brought'into contactwith the plungers 2 as said arm is disposed to the numerous In these drawings, certain specific details of construction have been shown for accom plishing probably the best results, but it will be evident that I need not be limited to such details otherwise thanto-the extent to which the appended claims restrict me.

I claim:

1. In'combinatioma plurality of latches,

a plurality of releasing members for said latches, a latch selecting member movable to a plurality of points adiacentv the several releasing members and shiftable toward and away therefrom for operating the same, and releasable means normally preventing shifting of said lock selecting member.

2. In combination. an arcuate series of shiftable latch releasing members, a swinging latch selecting member mounted upon an axis concentric with said series and shiftable toward and away from the independent releasing members thereof. and releasable stop means normally preventing shifting of said lock selecting member.

3. In comb nation, an axiall shiftable shaft, a non-shiftable shaft spaced from and disposed parallel thereto, actuating handles for the two shafts, a stop proiecting laterally fromone shaft. a stop plate carried by g the other shaft andhavinga notch through which said stop may passpthe latter being normally disposed to one side of said plate, a latch releasing member carried the shiftable shaft. and additional latch releasing members disposed on an arcuate path for coaction with the aforesaid member when the same is shifted. a I

4. In combination, an axially shiftable and rotatable shaft, releasable stop means normally preventing shifting of said shaft,

a latch se ecting member carried rigidly by one end of the shaft. and a pluralitv of latch releasing members from which said selector is normally spaced and into contact with which said selector may be forced when the stop means is released. r

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. r
